Racer's average driving speed
for a 4-hour trip was 45 miles per
hour. During the first three hours he
drove 40 miles per hour. What was his
average speed for the last hour of his
trip?
A 70 miles per hour
B. 60 miles per hour
C. 50 miles per hour
D. 65 miles per hour

Answers

Answer:

the answer is C.

Step-by-step explanation:

(50+40)/2=45

Answer:

so to average 45mph for 4 hours, he had to drive 4x45 miles total

4x45= 180miles

now we know he drove 120 miles (3x40) in the first 3 hours.

so he drove 180-120= 60 miles in the last hour.

60mph

How many moles are in 9.03 x 1023 Li atoms?
please help me

Answers

Answer:

1.5 moles

Step-by-step explanation:

number of moles = no. of particles / Avagadro number

therefore, number of moles. = 9.033 * 10^23 / 6.022 * 10^23

therefore, no. of moles = 1.5

There are 1.5 moles in 9.033 * 10^23 Lithium atoms.

A person places $1150 in an investment account earning an annual rate of 5.3%, compounded continuously. Using the formula V = Pe^{rt}V=Pe rt , where V is the value of the account in t years, P is the principal initially invested, e is the base of a natural logarithm, and r is the rate of interest, determine the amount of money, to the nearest cent, in the account after 10 years.

Answers

The amount of money that would be in the investment account with continous compounding would be $12,125.94.

What is the future value of the investment account?

The formula for calculating future value when there is continuous compounding is :

A x e^r x N

Where:

A= amount e = 2.7182818 N = number of years r = interest rate

1150 x (e^0.053) x 10 = $12,125.94

Ben hires some buses to take 768 people to a football match. Each bus can take 56 people.
Ben hires the least number of buses needed to take all 768 people. Then 19 of the people decide not to go to the football match. Does Ben still need all the buses he has hired? You must show how you get your answer.

Answers

Answer:

yes, he still needs all the buses he hired

Step-by-step explanation:

768 people/56 people per bus = 13.71, so 14 buses

768 - 19 = 749 people going

749people/56 people per bus = 13.37, so still need 14 buses

Answer:

Kindly check explanation

Step-by-step explanation:

Given :

Years of experience (X) :

Annual sales (Y) :

105

106

122

120

113

134

The estimated regression equation obtained is :

y = b0 + b1x

b0 = 82.82967

b1 = 3.46061

ŷ = 3.46061X + 82.82967

The change in annual sales for every year of experience is given by the slope value, b1 = 3.46061 = 3.5 (1 decimal place)

The Coefficient of determination R² = 0.8477 = 0.848 ( 3 decimal place).

The Coefficient of determination gives the proportion of explained variance.

About 84.8% percent variation in annual sales can be explained by years of experience of the sales person.

Using the regression equation :

ŷ = 3.46061X + 82.82967

Years of experience, x = 8

ŷ = 3.46061(8) + 82.82967 = 110.514

111 = (to the nearest whole number)

Step-by-step explanation:

Let "x" represent the measure of the indicated angle in each problem.

1. x = 135° (corresponding angles theorem)

2. x = 180° - 66° (same-side interior angles theorem)

x = 114°

3. x = 118° (alternate interior angles theorem)

4. x = 81° (alternate exterior angles theorem)

if y varies inversely with the square of x, and y=6 when x=4, find y when x=0.1

Answers

Answer:

9600

Step-by-step explanation:

y varies inversely with the square of x

y=k/(x^2)

for some non-zero constant k

y=6 when x=4

6=k/(4^2)

k=96

y=96/(x^2)

x=0.1

y=96/(0.1^2)

Answers

Answer:

Step-by-step explanation:

✔️9x + 10 = 15x - 2 (corresponding angles theorem)

Collect like terms

9x - 15x = -10 - 2

-6x = -12

Divide both sides by -6

x = -12/-6

x = 2

✔️y + (15x - 2) = 180° (same-side interior angle theorem)

Plug in the value of x

y + (15*2 - 2) = 180

y + 28 = 180

y = 180 - 28

y = 152
